Well, there has been whispers of a possible sTRX40 mDTX mobo over in the FormD-P1 thread &
@Wahaha360 is going on about wanting a 64c or 80c CPU & 3-slot GPU in a backpack, so maybe he knows something we do not...
I have the X570 mDTX board from ASUS, the Crosshair VIII Impact. Looking at that, I could maybe see:
sTRX40 socket flanked by four RAM slots (two to either side)
24-pin mobo, 8-pin EPS, 19-pin USB3, & USB3 Type-C connectors / headers along the right side of mobo (as usual)
SO-DIMM.2 slot for riser card with two PCIe Gen4 NVME M.2 SSDs (just like on the C8I)
Two PCIe Gen4 x16 slots (spaced for two 2-slot GPUs, so the second PCIe slot would be at the lower edge of the mobo)
A third PCIe Gen4 NVMe M.2 SSD slot between the GPU slots
A fourth PCIe Gen4 NVMe M.2 SSD slot on the backside of the mobo
This would allow a system with:
64c/128t CPU
128GB DDR4 RAM
8TB total Gen4 NVMe M.2 storage (no cables!)
Two top-end GPUs without the need for any riser card or bifurcation issues
Discuss...!!! ;^p
